How can you separate audio from a video clip in Premiere Pro?

To separate audio from a video clip in Premiere Pro, the most effective method is to right-click the clip and select 'Unlink.' This action allows you to separate the audio from the video, enabling you to manipulate them independently. Once unlinked, you can move, edit, or delete the audio without affecting the video track, which is particularly useful during post-production when adjustments are needed.

Dragging the audio track down to a new layer does not achieve the same effect, as it may not be recognized as a distinct track in the timeline. Using audio mixer settings is more about adjusting volume levels and effects rather than separating audio from video. Exporting the audio separately is a later step that occurs after the audio and video have already been linked or unlinked, making it inappropriate for the task of directly separating them within the editing timeline.
